   // if history.pushState is available, YouTube uses the history API
   // when navigation from one video to another, and tells the flash
   // player with JavaScript which video and which ads to show next,
   // bypassing our flashvars rewrite code. So we disable
   // history.pushState before YouTube's JavaScript runs.
